Please contact me if, while reading the French sources, things don't make sense. I know it's a Romance language and the book is written in a style that intellectuals in France are fond of, but which makes use of long-winded metaphors and bizarre expressions that require some familiarity with the language. I'm fluent, and yet I needed to consult an online French dictionary frequently while reading.
Elayne the best English language source for Onfray, and a great introduction to his intellectual legacy is Hedonist Manifesto. Here is my review:

I can't speak for him, but On happiness and worth, I'll refer you to the study by Dr. Christakis that I mentioned in my book, that showed that happiness is contagious, and the comparison between this study and another study on the correlation between money and happiness that showed that a happy friend adds aprox. $20,000 worth of happiness to our lives. So that is the "worth" of a happy friend.
Onfray does not revile utilitarianism and cynicism, for example, as much as he reviles Plato. He reserves most of his venom for Plato, and insofar as other philosophies/ers resonate with his counter-history of philosophy, he affirms them. For instance, he calls himself "a Nietzschean, insofar as he takes Nietzsche as a starting point in philosophizing". And he's a huge champion of THE BODY and its instincts and faculties (and ergo of libertarian individualism, versus the societal pressures and conventions that impose inauthenticity).
So -- whatever else we may say of him-- he has brought many thousands in Europe and the French speaking world to the study of Epicurus with his gospel of pleasure and his call to re-write history from an Epicurean perspective. Everyone that I've met in the Spanish world that knows about Epicurus is pretty familiar with Onfray. By contending with his words, we inject ourselves into thousands of discussions about Epicurus that are happening all over Europe and Latin America.
